WRENCH.

SPECIFICATION forming part of Letters Application filed August 21, 1903.

To all whom it may concern/.1,

Be it known that I, CHARLES DE Wrr'r ONEIL, a citizen of the United States, residing'at Harlan, in the county of Shelby and State of-Iowa, have invented certain new and useful Improvements in Wrenches, of which the following is a specification.

This invention relates to the class of wrenches of the type embodying the use of a nut provided'with an interrupted thread by' which a;,fmpvable-jaw' carried by the wrench maybe quickly adjusted, so as to clamp an article, and locked at the desired adjustment without necessitating the revolution 'of the nut a greater or less number of times, dependent upon the extent of movement of themovahlejaw. 1 I

I am aware that it is not; nevvfto provide quick acting wrenches having? distorted threads and have as my object'to improve upon the structures heretofore patented in this art'- by providing. a locking element'which by a minimum degree of movement infe'ither'direction will either lockthemovable' jaw at an ascertained adjustment or, permit movement of the jaw along the shankfoffthe wrench..

.For a full description of.the invention and the merits" thereof and also to acquire a knowledge of the details of construction of the means for effecting the result reference-is to be had to thejfollo'wing description and drawi g hereto attachem:

'While the essential and characteristic fea tures of the invention are susceptible of modification, still the preferred embodiment of the; invention is illustrated inthe accompanying drawings, in which+ Figurel= is a erspettl 1% view ofiawrench embodying my inveution Fig. 21s a side elevation showing. the "lock element in engaging' relation. withthe shankio'f thewrench to fix the jaw'at an ascertained adjustment.- Fig. 3 is-a vertical sectional view through the wrench, Fig. 4 is.a detail perspective View of my lock element. i I

Serial No. 170525- (No model.)

to in the following description and indicated in all the views of the drawings by the same reference characters.

The wrench as regards the general structure thereof is of ordinary type embodying t'he use of a handle 1, a fixed jaw 2, carried by the -toothed shank 3, and a movable 'jaw 4.

The lock element which constitutes my invention is disposed upon the movable jaw 4: and.

consists of a nut 5, provided with right-angularlydisposed faces 6 and 7 The face 6 is smooth, so that when the lock element is manipu-lated'so as to bring this face adjacent the toothed shank the movable jaw will be free for slidable movement upon the said shank. The adjacent face 7, however, is provided with longitudinal teeth 8, which are adapted for cooperation with the toothed shank 3 to lock the movable jaw at a relative adjustment as regardsthe fixed jaw. The nut 5 is rotatably mounted upon the jaw 4, and either of. the faces 6 or 7 may be brought adjacent the, toothed shank by giving the nut a quarter-turn by manipulation of the finger-piece 9,. disposed upon the nut.

provided ,a stop 10, which limits the movementl of the nut when throwing the smooth face into a position adjacent the toothed shank.

The locking device,- as before described, provides a construction'of wrench in whichthe movable jaw is adapted for a quicker looking engagement with the toothed shank and likewise more readily adapted to be thrown into a position permitting free movement of the movable jaw than are thestructures of wrench embodying the nut element having the interrupted-thread form.
